How do humans speak and hear? And how can this exquisite a hallmark of humanity falter during the lifespan. This course will consider how moving our bodies—our tongue, larynx, and lips—creates sound that encodes the informational substance of human language. This course introduces students to thinking about spoken language communication as a physical act taking place in a dynamic and social context in health and in breakdown.
After an introduction to vocal tract anatomy, students will take an audio-visual tour through the varied speech sounds that languages of the world use—from vowel and consonant sounds to clicks to tone. We will practice phonetic transcription and give a go at transcribing less familiar varieties of English. We work toward a basic grasp of speech acoustics and the physiology of human hearing, while appreciating the abstract nature of human speech perception We look at how bilingual speakers juggle their multiple languages. This body of phonetic knowledge is deployed in a consideration of how diseases and disorders can affect the ability to speak and hear. For example, we learn about voice disorders, stuttering, oropharyngeal cancer, deafness, and hearing loss. We finish by considering implications of what we have learned for speech technologies, including cochlear implants, speech synthesis, and automatic speech recognition.
If you’re interested in linguistics, cognitive science, voice and speech, speech technology, or human health, this GSEM seminar might be up your alley. All backgrounds and interests are welcome!

Engagement: For course grades that are computed to be 'on the bubble,' in-lecture engagement and participation may be taken into account in tipping a grade upward or not.
Assignments: Some assignments will involve the use of a computer; some will be writing and/or analysis oriented. Assignments will be released at least one week prior to their due date.
Late homeworks are not accepted with the following exception: A request to the professor in advance to use your course 'TimeBank' allows for one two-day extension during the semester to be applied to Homework 1-3 only—not applicable to tests, interview report, or oral presentation.
The course will be graded on a curve (applied to final grades): roughly top 45% As, next 45% Bs, next 10% Cs and below. The curve will not however move grades down.
Tests cannot be ‘made up’ or taken early unless arrangements with the instructor are made in advance and are due to documented unavoidable circumstances (aka an emergency).
All assignments are to be done **independently**, not in teams, not with partners, not in collaboration. Copying or collaborating on homework assignments (or exams) will be considered a violation of Academic Integrity (see further below).
This course aims to develop creative, analytical, and critical thinking skills. Therefore, all assignments should be prepared solely by the student working individually. Students may not have another person or entity complete or prepare any portion of an assignment. Therefore, using AI-generated text, code, or other content is prohibited in this course, will be identified as plagiarism, and will be reported to the Office of Academic Integrity. If I believe material submitted by a student was produced by A.I. (e.g. ChatGPT), I reserve the right give the student an immediate impromptu oral exam on the same material.
with lecture-by -lecture weekly schedule and Readings and Assignments by Week
Topics are expected to include:
The Human Vocal Tract and how it is used to make the sounds of English and other languages

Slack and Email: In addition to the utility of Slack, it is useful if we can communicate with each other using email. In this way, you can be advised of changes, and I can be advised of any problems that you encounter. Please know that for this class I will expect you to check your email. In case you are unfamiliar with email, communications should be respectful and grammatical.
Students with symptoms of illness should not be in the classroom. If you are ill, let me know and we will work together to address continuity of education. If your symptoms are consistent with Covid-19, you should arrange to test through MySHR.
Students are expected to comply with all aspects of USC’s COVID-19 policy as extant at any given time, including its masking policy. Failure to do so may result in removal from the class and referral to Student Judicial Affairs and Community Standards. If we find ourselves needing to be remote, here are Professor Byrd's Netiquette expectations for the virtual classroom.
For students enrolled in classes that will be taught in-person, the default attendance expectation is in-person. Students who present an OSAS accommodation that permits them to take the class online-only will be accommodated. Similarly, we want to support and accommodate students who test positive for COVID or are required to self-isolate due to a high-risk exposure. That said, there should be no expectation that this class will be recorded, though it may be recorded at times for students who cannot be present due to illness.
Emergency Preparedness/Course Continuity in a Crisis—New Students are automatically signed up for TrojanAlerts. “In case of a declared emergency if travel to campus is not feasible, USC executive leadership will announce an electronic way for instructors to teach students in their residence halls or homes using a combination of Blackboard, teleconferencing, and other technologies. See the university’s site on Campus Safety and Emergency Preparedness.”

Academic Integrity
The University of Southern California is foremost a learning community committed to fostering successful scholars and researchers dedicated to the pursuit of knowledge and the transmission of ideas. Academic misconduct is contrary to this fundamental mission and includes any act of dishonesty in the submission of academic work (either in draft or final form), as well as cheating, plagiarism, fabrication (e.g., falsifying data), knowingly assisting others in acts of academic dishonesty, and any act that gains or is intended to gain an unfair academic advantage. Students are expected to uphold the highest standards of academic integrity in all coursework.
This course follows the expectations for academic integrity as stated in the USC Student Handbook. All students are expected to submit assignments that are original work and prepared specifically for the course/section in this academic term. Students may not submit work written by others or “recycle” work prepared for other courses without obtaining written permission from the instructor(s). Students suspected of academic misconduct will be reported to the Office of Academic Integrity.[1]
Other violations of academic misconduct include, but are not limited to, cheating, plagiarism, fabrication (e.g., falsifying data), knowingly assisting others in acts of academic dishonesty, and any act that gains or is intended to gain an unfair academic advantage.[2]
Academic dishonesty has a far-reaching impact and is considered a serious offense against the university. Violations will result in a grade penalty, such as a failing grade on the assignment or in the course, and disciplinary action from the university, such as suspension or expulsion.
For more information about academic integrity see the Student Handbook, the Office of Academic Integrity’s website, and university policies on Research and Scholarship Misconduct.
[In this course, unless specifically designated as a ‘group project,’ all assignments are expected to be completed individually. In this class, you are expected to submit work that demonstrates your individual mastery of the course concepts.] Please ask me if you are unsure about what constitutes unauthorized assistance on an exam or assignment, or what information requires citation and/or attribution.
USC has policies that prohibit recording and distribution of any synchronous and asynchronous course content outside of the learning environment.
Violations of Academic Integrity: Recording a university class without the express permission of the instructor and announcement to the class, or unless conducted pursuant to an OSAS accommodation. Recording can inhibit free discussion in the future, and thus infringe on the academic freedom of other students as well as the instructor. (Living our Unifying Values: The USC Student Handbook, page 13).
Violations of Academic Integrity: Distribution or use of notes, recordings, exams, or other intellectual property, based on university classes or lectures without the express permission of the instructor for purposes other than individual or group study. This includes but is not limited to providing materials for distribution by services publishing course materials. This restriction on unauthorized use also applies to all information, which had been distributed to students or in any way had been displayed for use in relationship to the class, whether obtained in class, via email, on the internet, or via any other media. Distributing course material without the instructor’s permission will be presumed to be an intentional act to facilitate or enable academic dishonestly and is strictly prohibited. (Living our Unifying Values: The USC Student Handbook, page 13).
Course evaluation occurs at the end of the semester university-wide.
Accommodations
(from USC Center for Excellence in Teaching https://cet.usc.edu/teaching-resources/syllabus-template/)
OSAS is responsible for the determination of appropriate accommodations. Once a student has completed the OSAS process (registration, initial appointment, and submitted documentation) and accommodations are determined to be reasonable and appropriate, a Letter of Accommodation (LOA) will be available to generate for each course. The LOA must be given to each course instructor by the student and followed up with a discussion. This should be done as early in the semester as possible as accommodations are not retroactive. More information can be found at osas.usc.edu. You may contact OSAS at (213) 740-0776 or via email at osasfrontdesk@usc.edu.
